- The SYNERGIC PULSED TIG DC
enables a highly concentrated arc to be obtained. It is a very sta
-
ble arc and moves the pool with strong fluctuations. It is ideal for use in spot welding and the creation
of thin fillets. It is recommended for thin gauge sheets and in particular where a very stable arc is
required (viscous pools)
In this mode, the welding parameters are pulsed: BASE CURRENT; PEAK TIME; PULSED FRE
-
QUENCY are only displayed and cannot be modified.
- PRE-GAS TIME
○ Time of gas delivery before the arc strike.
○ This adjustment is required when fixing points must be created or when welding in hard-to-reach
positions that call for the presence of inert atmospheres before striking the arc.
-
Consequences of a higher value:
•
This parameter allows a shielded environment to be created, thereby eliminating contaminants
at the start of the welding pass.
- STARTING CURRENT
○ Unit current output value immediately after the arc strike. The value of this parameter can be
set as a percentage of the welding current or as an absolute value expressed in Amperes. The
parameter is displayed but it is not used during the welding process when the following setting is
present: MULTI TACK = ON The usefulness of having an adjustable initial welding current is that
of avoiding welding the part with excessively high current values and thus potentially damaging it.
Particularly useful when welding thin sheets.
- SLOPE UP
○ Time during which the current changes from the starting value to the welding value by means of
a slope.
○ This setting is used to avoid damaging the edges of the joint with excessively high current values
at the moment of arc striking. The value of the main welding current is increased gradually in order
to control the uniformity of material deposition and weld penetration. The parameter is not used
during the welding process when the following setting is present: MULTI TACK = ON
- WELDING CURRENT
○ This parameter regulates the primary welding current value.
- MAXIMUM CURRENT WITH REMOTE CONTROLLER
○ Maximum output current value that can be achieved with remote controller external reference.
- SECOND CURRENT B-LEVEL
○ With a rapid press and release (less than 0.5 seconds) of the torch trigger during welding, the
output current value switches to the value set by means of the “B-level second current” parameter.
○ This function makes it possible to avoid interrupting the welding process when the geometry of
the workpiece changes; alternatively, the welding current can be reduced to decrease heating of
the part if it becomes too hot during execution of the welding process.
○ In DC TIG welding, the parameter is useful when welding different gauge workpieces during the
same pass; when moving between different gauges the output current can be changed simply by
pressing the torch trigger.
- BASE CURRENT
○ Pulsed wave minimum current.
-
Consequences of a higher value:
•
- Faster creation of weld pool.
